Dion Alan George Waller (born 6 January 1974 in Tūrangi) is a former New Zealand rugby union footballer.
He was one of the leading locks in New Zealand rugby at provincial level with great lineout attributes, but never got a real opportunity to play internationally as he left New Zealand to play in Japan.
He made his debut for King Country in 1995 after being selected for the New Zealand U21s tour to Argentina.
Dion retired in 2008 and went straight into giving back to rugby in New Zealand by coaching Aotea College U15s in Porirua.
